374P - Influence of sex on safety and efficacy in BRAF-V600E mutated metastatic colorectal cancer (mCRC) treated with encorafenib-cetuximab +/-binimetinib (E-C+/-B)
- Francisco Javier Ros Montana (Barcelona, Spain)
Abstract
Background
Methods
Patients (pts) with mCRC candidates for E-C+/-B were included. Clinical data was collected prospectively. Clinical outcomes were calculated using survival Kaplan-Meier curves.
Results
From 2017 to 2021, 59 pts with mCRC were treated with E-C+/-B at our institution, 23 males (5 E/C/B, 18 E/C) and 36 women (15 E/C/B, 21 E/C). Overall, mOS and mPFS were 11.5 and 5.4 months, respectively. mOS in females was 12.52 vs 9.76 months in males (HR 1.21 95%CI 0.65-2.25 p 0.56). No significant differences were observed between men and women treated with the doublet (11.47 vs 11.53 months). Of note, women treated with the triplet showed a clear trend towards better mOS (20 vs 9 months, HR 3.22 95%CI 0.91-11.41 p 0.07) and mPFS (8.44 vs 5.72 months, HR 1.44 95%CI 0.49-4.24 p 0.5). Pts with G3-4 toxicities had significantly worse mOS (12.52 vs 6 months, 95%CI 1.52-10 p 0) and mPFS (5.62 vs 3.84 months 95%CI 1.13-6.60 p 0.03). Of note, G3-4 toxicities were more frequent in females (28% vs 17%). Globally women required higher dose modifications than males with both the doublet and the triplet (67% vs 60% and 71% vs 39%, respectively). When the doublet was used women had more arthralgias, pancreatitis, and cutaneous toxicity (any grade) being asthenia, liver, renal and cutaneous toxicity (any grade) more frequent with the triplet.
